scipy.io.savemat

scipy.io.savemat(file_name, mdict, appendmat=True, format='5', long_field_names=False)

Save a dictionary of names and arrays into the MATLAB-style .mat file.

This saves the arrayobjects in the given dictionary to a matlab style .mat file.

file_name : {string, file-like object}

Name of the mat file (do not need .mat extension if appendmat==True) Can also pass open file-like object

m_dict : dict

dictionary from which to save matfile variables

appendmat : {True, False} optional

True to append the .mat extension to the end of the given filename, if not already present

format : {‘5’, ‘4’} string, optional

‘5’ for matlab 5 (up to matlab 7.2) ‘4’ for matlab 4 mat files

long_field_names : boolean, optional, default=False

False - maximum field name length in a structure is 31 characters

which is the documented maximum length

True - maximum field name length in a structure is 63 characters

which works for Matlab 7.6
